PVC foam, or PolyVinyl chloride foam, finds significant application in the field of wind turbine blades. It is used in Blade shells, nacelles, spinners, root section. For example, it offers good durability and can withstand various environmental conditions. Additionally, PVC can provide some degree of flexibility, which is beneficial for the functionality of the blades. However, its usage also needs to take into account factors such as weight and cost-effectiveness. 

Overall, PVC plays a role in enhancing the performance and characteristics of wind turbine blades, but further research and development are constantly being carried out to optimize its application and overcome potential limitations.​​​​​​​
